Specification of Letters Patent.

Application filed August 10, 1916. Serial No. 114,128.

' such an engine which may be used to employ the exhaust-gases to serve as heatingmeans for kerosene or heavy hydrocarbons in volatilizing them to be suitable for the ordinary consumption of the engine at all times. This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which:

Figure 1 is an elevation of the inner face i of the detachable cylinder-head which con tains within its structure the internal means .for gasifying the vapors of kerosene or crude oils.

Fig. 2 is an under plan view of said cylinder-head.

Fig. 3 is a transverse horizontal axial section of said cylinder-head.

Fig. 1 is a vertical transverse section of a carburetor formed and adapted to ooo crate with my improved cylinder-head a ove illustrated.

Similar numerals of reference denote corresponding parts throughout the several views.

The cylinder-head 1 is adapted to be detachably secured over the combustion-chamber end of the cylinder of an internal combustion engine, and has ports 8 and 9 adapted to seat the valve-heads 2 and 3 respectively for admission of fuel or exhaust of the utilized gases of combustion.

Referring now to said Fig. 4, the carbucontains means for introducing a supply of either gasolene or kerosene. A channel 19 serves for the introduction of a preliminary charge of gasolene to start the engine when drawn in the usual way from the chamber 13 with a mixture of air from the port 23 through the passage 10 of the cylinder-head past the valve-head 2. This conduit 19 is contracted by means of an inserted orificed plug whose orifice is controlled in delivery by means of a needle valve 20. Below the delivery-plug mentioned, another and simu lar delivery-plug 21 is seated in a conduit in the carbureter which is in communication with a supply of kerosene controlled by a valve not shown. Kerosene vapor is drawn up through the chamber 13 and said chamber 10 by the action of the engine in forming a vacuum at the inlet-port, the vapor being also mixed with air through the port 23 in a like manner. To gasify the comparatively large vapor particles of the kerosene, I employ the following means. The carbureter 12 contains a chamber 14:, controlled by means of a valve 15, and which leads from the port 18 of the carburetor by way of the intermediate passage 24 around and past a baffling partition 16 to the exhaust-port 5 of the cylinder-head 1. By referring to Figs. 3 and 1 it will be seen that the hollow of the cylinder-head is so divided by means of internal partitions that the inlet-chamber 10 is separated in said head from the exhaustchamber 11, the latter chamber lying side by side with said chamber 10. The exhaust chamber 11 is divided into two diverging delivery-conduits 5 and 6, the smaller conduit 5 only being in communication with the chamber 14: of the carbureter.

The exhaust-gases are forced from the conduit 5 into the said chamber 14 past its valve 15, whence the gases pass downwardly to the vent-port 18 entirely about the inner partition which separates the chamber 13 therefrom, and past the horizontal bafilingpartition 16 which extends about half-way across the intermediate passage 24.

The heat of the exhaust-gases is conducted tl'flough the comparatively thin artition wa 5 both of the oarbureter and o the chambered cylinder-head 1, and heats the mixed gas or vapor and air in the channels leading to the inlet-valve port 8 so highly that the particles of kerosene are broken up and reduced to a gas-like condition suitable for efiective combustion in the engine; My improved cylinder-head gasifying-means therefore is contrived to be efiective for the purpose when in cooperation with a carbureter since the gasifying operation is kept up to the very moment when the gases pass the inlet-port of the engine. The gas cannot become cooled. and condensed or driven back because of this construction, while the division of the exhaust-gases provides a better clearance for them.

Having described my invention, what 1 claim as new, and desire to secure by Letters Patent, is:

l. A gasifier for an. internal-combustion engine, consisting of a detachable hollow head for the cylinder, said head having separated chambers in communication with the --oo nbustion-chamber of the engine by means of valve-controlled ports, one of the chammenses bers being adapted to receive the exhaustgases of the engine, and said head having means for dividing the voided gases into two streams divergently, of which one stream is caused to pass over the'wall separating said chamber from the'other or inlet-chamber of the head.

2. In an internal-combustion engine, a head having an exhaust-chamber in communication with the combustion-chamber of the engine by means of a valve-controlled port, said chamber being formed into divergent conduits, and said head having exit-ports for said conduits.
